1 GRAIN-SHOCKING MACHINE.

Specification of Letters Patent. Patented Man 13, 191% Application filed January 6, 1913. Serial No. 740,484.

line, respectively, in the county of Cook and the county of Rock Island, respectively, and State of Illinois, have invented certain new and useful Improvements in Grain-Shocking Machines, of whichthe following is a full, clear, and exact specification.

Our invention relates to grain shocking machines.

In grain shocker-s of the swinging fork means therefor;

Fig. 3 is an elevation of the means shown type wherein the sheaves delivered to the cradle by the fork are bound in the shocker cradle while in prostrate position and the cradle is then raised to vertical position to discharge the bound shock, it has been found that under certain grain conditions the fork delivers sheaves to the cradle with their butts protruding too far through the vertical end tines thereof. This has resulted in deleteriously afiecting the standing quality of the shock as when the cradle is dumped the ends of these sheaves are crumpled against the ground as the cradle moves to .shock discharging position in such a manner as to cause the shock to fall or tilt toward the shocker as the latter moves forward. In certain other conditions where the grain is short, difliculty has also been experienced in setting shocks formed of short sheaves, due to the fact that with the cradle set for long grain the sheaves have too great a range of movement prior to the time they strike the ground.

Our invention has for its object to adjust the shocker truck vertically in an improved manner whereby this tendency toward variation in the standing qualities of shocks of long or short grain is effectually prevented. A more specific object of our invention is to adjust the frame and running gear of a shocker relatively to each other .in an im proved manner so that the height of the shocker frame and the device or devices carried thereon may be'readilychanged as desired. We attain this object by providing improved positively acting means operatively connected between the shocker frame and the running gear which are readily adjustable to move the frame to any one of a plurality of positions and automatically lock the parts in any desired position.

In order to clearly and fully disclose our invention we have illustrated one embodiment of the same in the accompanying drawings, wherein the same is shown used in connection with a grain shocker frame of the type described and claimed in our copending application Serial No. Jan. 6, 1913. It is to be understood, how ever, that our invention is not limited to the embodiment; shown herein, but may be modified without departing from its spirit.

Figure 1 is a rear elevation of the frame.

Fig. 2 is a sectional view of the adjusting in Fig. 2. The frame shown includes a horizontally disposed U-shaped member 1 adapted to support grain shocking or other mechanism;

vertically disposed U-shaped members 2 and 3 carried thereby and rigidly attached thereto, and a pair of vertically extending parallel arms or standards 4 of channel construction rigidly attached to the opposite sides of the member 1 and themselves adjustably and slidably attached, as hereinafter described, to cooperating rotatable wheel standards 5 connected .together by a rigid link 5, forming apart of the runninggear' and provided at their lower ends with transport wheels 6.

The standards 4 are each provided with a longitudinally extending opening or slot 7 near their ends, and carry a slotted plate 8 fixed thereto, as by bolts 9, so that the slot 10 therein is substantially over the'slot or opening 7 in the standards l. On opposite sides of this slot the plate 8 is provided with lugs 11 in which a pinion 12, is rotatably mounted on a shaft or spindle 13. 'As.

sired relation to the wheel standard 5 by lips 14: on theupper end of the rack member 14;

740,481, filedpreferably protruded at and by a collar 4: carried the frame and slidable on the lower portion of the wheel standard 5.. In order to automatically lock the pinion in any desired position, we provide an underlymg dog or pawl pivoted on a spindle 18 ournaled n lugs 19 formed on the plate 8. The pinion-engaging end of thisdog is elongated and substantially rectangular shape so that'in locking position erated torelease the pinion, an elongated shank or handle 20 is provided upon the same. Further, in order that the dogmay be automatically thrown into engagement with the pinion, acoiled spring 21 is positioned between this handle and the standard 1 at a point beneath the pivot point of the d0 Further, in order that the pinion 12 may be readily operated, its spindle 13 is one side and provided with one or more lugs 22, so that the same may be rotated by a suitable key or crank.

The operation of the construction shown is as follows: When it is desired to raise the frame, as, for instance, when it is found that the butts of the sheaves protrude too great distance through the end tines of the cradle, it is only necessary to attach a suitable crank or key to the end of the desired spindle 18 and rotate the same so that the'pinion 12 travels upon the rack'14. Due to the'action of the spring 21, the pawl 17 automatically locks the pinion in each position. Obviously, when it is desired to lower'the frame, it is only necessary to press in the handle 20 of the pawl to throw the latter out of engagement with the pinion, whereupon the frame is readily movable downward to the desired position. When this position is reached and pressure upon the handle 20 is removed, the dog 17 automatically returns to locking position.

is to be noted that in the construction shown, the frame maybe readily adjusted either upward or downward with respect to the standards irrespective of the angular displacement of the wheels. Further, in each position the frame isse'curely locked to the standards due to the action of the pawl which is automatically thrown in by its springs so that it underlies one ofthe teeth of the pinion and providesa substantial abutment. It is furtherto be noted tha when it is desired to lower the'fran'ic, it 7 is only necessary to release the pawl from its engagement with the pinion by a'relatively short movement of the pawl handle whereupon the frame is freely movable by gravity to the desired position and is positively and automatically locked in this position upon the release of the pressure upon the'handle.

\Vhile we have herein specifically described this embodiment of our invention, it

is, of course, to be understood that the form shocker frame'carried thereby and open;

atively connected to said standard, a rack melilbe'rf'cm'l'led on e of a d members forming a journal for said standarch a pinion carried on the-other member cooperating with said rack member to vary the relative position 'of said members, and {means for locking the parts in posltion'.
